Total Ozone Mapping Spectrometer (TOMS) Ozone, Aerosol, UV and Reflectivity Data and Images from Earth Probe-TOMS (EP-TOMS)

The Earth Probe-Total Ozone Mapping Spectrometer (EP-TOMS) spacecraft
was launched on July 2, 1996 from a Pegasus rocket. The launch of
EP-TOMS continues the global measurements of ozone that began with the
TOMS instrument on Nimbus-7 and Meteor-3 (1978-1994).

EP-TOMS ozone data is obtained 3 or 4 times per day and is processed to
ASCII data (in Dobson units).

Nimbus-7, Meteor-3, and ADEOS TOMS data are also available.

地球探测-总臭氧测绘光谱计（Earth Probe-Total Ozone Mapping Spectrometer，简称EP-TOMS）航天器于1996年7月2日由飞马座运载火箭发射升空。此次EP-TOMS的发射，延续了雨云7号（Nimbus-7）与流星3号（Meteor-3）搭载的总臭氧测绘光谱仪（Total Ozone Mapping Spectrometer，简称TOMS）于1978年至1994年间开启的全球臭氧总量观测工作。
EP-TOMS的臭氧数据每日可获取3至4次，经标准化处理后输出为ASCII格式数据，单位为多布森单位（Dobson units）。
雨云7号、流星3号及先进地球观测卫星（ADEOS）搭载的TOMS数据同样可供使用。
